Issue with org.apache.felix:maven-bundle-plugin and Export-Package/Import-Package

Question

I am trying to configure how packages are imported/exported by the maven-bundle-plugin by specifying the * wildcard. The config below results in no package being exported or imported...

Anyone has any clue?

EDIT: The exact message I get is

karaf@root> package:import  181
spring-batch-core (181): No active imported packages.

because the bundle is not active.

EDIT: When I start the bundle I get this:

karaf@root> osgi:start 181
org.osgi.framework.BundleException: Unresolved constraint in bundle osgi.org.springframework.batch [181]: Unable to resolve 181.0: missing requirement
 [181.0] package; (package=bsh)

EDIT: If I just use the spring batch core, I systematically get this error on startup:

karaf@root> Exception in thread "SpringOsgiExtenderThread-2" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'j

Hello Eugene. It seems it is exporting and importing everything. [see here](http://pastebin.com/HTB7rQUM) — balteo, Aug 14 '12 at 11:23
could you still SHOW the generated file? it is in your jar that you generated. — Eugene, Aug 14 '12 at 11:27

Why do you need o do this? The spring-batch-core is already an OSGi ready bundle, isn't it? Check the MANIFEST.MF from that jar. I just looked up the 2.0.4.RELEASE for spring-batch and from what I see it is already a bundle.

@balteo do you have a jar that actually exports this class? There are commands under karaf that will tell if at least some bundle exports a package/class or not. – Eugene Aug 14 '12 at 12:14
I do have a bundle that exports this package. Can you be more specific regarding the Karaf command you are referring to? – balteo Aug 14 '12 at 12:20

Eugene: Thanks. As you can see from my post I already use the package:export/import command. What I am specifically looking for is a command to **set** the packages imported/exported... – balteo Aug 14 '12 at 12:28
@balteo "I do have a bundle that exports this package" how do you know? What command did u run and what was it's output. Because from the logs Karaf can't see this package. – Eugene Aug 14 '12 at 12:35
I ran package:export 57 (57 being the xstream bundle). I am adding the results of this command to my post. Bear with me... – balteo Aug 14 '12 at 12:42
I see the problem thus: `com.thoughtworks.xstream.io` is exported by 57 (being xstream) but not imported by 85 (being spring batch core) hence my problem... – balteo Aug 14 '12 at 12:45
